Problems solved by technology

[0002] Special textiles have strict flammability standards. For example, the flammability standards for children's pajamas generally require their limiting oxygen index (LOI) to be above 25. Therefore, flame-retardant synthetic fibers have been developed. However, these fibers are achieved by adding additives. Its effectiveness reduces the strength of the fiber, increases the brittleness, poor wearing comfort, and the overall effect of the fiber alone spinning fabric is not ideal

preparation example Construction

[0008] The preparation method of the present invention is the following steps:

[0009] ①, Cleaning: put all the flame-retardant functional fibers on the plucking machine in a certain order, and mix and grab. It is recommended to use a reciprocating automatic cotton plucking machine. The remaining 2-3 different natural fibers or cotton-type chemical fibers should be grabbed separately , into rolls;

[0010] ②. Carding: The obtained functional fiber rolls and 2-3 different natural fiber or surface chemical fiber rolls are carded into strips for drawing;

[0011] ③Drawing: Three drawing processes are used, that is, the first drawing is mixed, and the second drawing is carried out. When the first drawing is made, the arrangement sequence of the fiber strips is arranged according to the number of blended fibers. For example, three kinds of flame retardant functions are used. Drawing of fibers and 3 different natural fibers or cotton-type chemical fibers: functional fiber a, natur...

Embodiment 1

[0015] Ingredients: natural cotton fiber 31-33mm25%, viscose fiber 1.44dtex×38mm15%, polyester fiber 1.67dtex×38mm15%, flame retardant polyester 20%, chlorinated fiber 15%, Toyobo Heim flame retardant polyester fiber 10%;

Embodiment 2

[0022] Ingredients: 30% of natural cotton fiber 31-33mm, 20% of polyester fiber 1.67dtex × 38mm, 20% of flame-retardant polyester, 15% of flame-retardant polyvinyl chloride fiber, 15% of Toyobo Heim flame-retardant polyester fiber, and its preparation method is the same as the embodiment one.

[0023] In summary, the flame-retardant yarn of the present invention is made of natural cotton fiber, polyester fiber, flame-retardant polyester, and flame-retardant polyvinyl chloride fiber, etc., and has good flame-retardant performance, high weaving efficiency, and improved product quality. production value.

Abstract

The invention provides a novel weaving idea of a flame retardant yarn variety fabric and process, through a reciprocating automatic plucker to clean cotton, using the processes of mixing a head and a channel, and twice drawing, a drawing sliver which is spun into yarn through roving yarn and spun yarn, after being twisted, the yarn is changed into wire. Using the fiber blending, the comfortable wear is guaranteed and the flame retardant efficacy is possessed, simultaneously, the cost is properly reduced, the weaving performance is capable of being obviously improved, the weaving effect is improved above 92 percent, simultaneously, the strength of the fiber is increased, the brittleness is increased, the wear comfort is excellent, the production process is simple, the weaving effect is high, the production value of a product is improved, and the economic and social benefits are excellent.

Description

technical field [0001] The invention relates to a weaving method for a blended yarn fabric, in particular to a weaving method for a blended yarn fabric with flame-retardant function. Background technique [0002] Special textiles have strict flammability standards. For example, the flammability standards for children's pajamas generally require their limiting oxygen index (LOI) to be above 25. Therefore, flame-retardant synthetic fibers have been developed. However, these fibers are achieved by adding additives. Its effectiveness reduces the strength of the fiber, increases the brittleness, and makes the wearing comfort poor, and the combined effect of the fiber's separate spinning fabric is not ideal. Contents of the invention [0003] The purpose of the present invention is to provide a weaving method of flame-retardant yarn fabric which is comfortable to wear and has obvious flame-retardant effect. [0004] The technical scheme provided for realizing the present invent...
